Abstract (en)
[origin: US2013315212A1] Interference between reference signals from user equipments in a wireless network, the method may be reduced by using a received time shift value from a node in the wireless network. An interference randomization technique may be applied to a reference signal and a sequence may be generated based on the reference signal to which the interference randomization technique has been applied. A processed reference signal may be derived by applying a time shift based on the time shift value to the sequence. The processed reference signal may be transmitted to the node. Related systems, methods, nodes and wireless devices are also described.
